VGASLSTEAM, OR WATER VALVE.

To all whom t 11m/y concern:

Be it known that we, LEO H. FREUND, a citi zen of AnstriafHungary, yresiding in the city ofl ew York, State of New York, and EUGENE F. FREUND and GEORGE F. KUETT, citizens of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Valves for Gas, Water, Steam, dac., of which the followingis a specification.

Oui` invention relates to improvements in valves in which the valve after being partially closed closes the remainder of the way automatically; and the objects of our improvements are, first, to provide for a gasvalve which will automatically extinguish itself when turned too low; second, to provide for a safety gas-burner valve in that it' cannot be turned low and liable to go out when pressure is relieved by opening another jet or blown out; third, to remove the lia# bility of accidentally opening the valve, and,

fourth, to Vconstruct a valve for liquids or steam in which the wear on the valve is removed from its ground-seat to some other part. We attain these objects by the mechanism illustrated in the accompanying drawings, in whichn Figure 1 is a side section of our invention with an ordinary gas-burner attached. Fig. 2 is an end view of our inventionwith part of the case shown in section; Fig. 3, a side View of another style of valve.; Fig. 4, a front view of Fig. 3, except that the valve is open. Fig.v

5 is an enlarged detail of upper part of valve; Fig. 6, a sectioned ground plan of Fig. 4; Fig.

7, a detailed l'elevation of the case; Fig. 8, an-

enlarged detail showing several positions of the valve. Figs. 9 and 10 are two views ofl the center slide of the valve Fig. 11, a ground plan of Fig. 1 with the burner not shown.

Fig. 12 is an ordinary burner connection fori lgas used in connection with Fig. 3.

Similar figures refertosimilarparts throughout the several views.

In the drawings the valve consists of a case 24, in which there is a piece (shown in Figs. 9 and 10) marked 23. The outside of the largest part iits perfectly in sliding contact with the inside of the case 24. The slope of the case corresponds exactly with the cone-shaped part 22 of the piecev23, and the hole 32 in the case also fits oventhe lower part of 18 in sliding contact. In the bottoni -oi' the case 24 a cap or plug 35 is screwed, on which there is a pin 36, and in the bottom oi" the. piece 23 there is also a pin 33., Over each of these pins 33and 36 each end of a spring 6 is held in position. On theupper part of 18 of the piece 23 there is a thread, 'on which is screwed a bracket 4, in which the small lever ork handle 3 is secured. YOn this sainevthread an ordinaryppillow 1, with the tip2,is screwed down to the piece 4. The case Zei'has a side connection 1l, in which an ordinary pipe 12 is screwed.

Fig. 3 shows a valve with connections on opposite sides in which pipes can be screwed for other fixtures.

In the center slide 23 there is a hole 19, breaking into the cross-hole 2O, which re' ceives the gasat one of its ends. In the'part 5 there is a slot, in part of which the lever 3 Y can move horizontally from the part marked 30 to the base of the' vertical part 2S and from the point 2S to the part 29 vertically, one sideis run to the verticalpart at 29. There is also a small indentation 28 in the bottoni of the vertical slot and at the end of the horizontal slot. Figs. 5 and 8 `show the center hole 19, and the dotted lines running crosswise indicate the different positions of the hole 2O as the valve is turned.

25 represents the' inlet-holein the casegl, the position of 2() in relation to'25 when the valve is open; 16, the position of the valve in relation to 25 when nearly closed, and 17 when closed altogether. The positions ofthe leverl indicated by 13, 14, and 3 correspond with the positions 15, 1G, and 17 of the position indicated by 13 in Fig. 5, and the valve' is open and the gas is passing freely and divrectly through the valve horizontally,

ICO

down to the piece e or like, Fig.` 3, with no thread on the top. The lever 3 is inserted di rectly into the piece 2l and lying in the slot in the piece 5. The spring 6 is then placed in position over the pin 33 and the pin 36 of the cap 35, which is screwed in the bottom of the case 24. A wheel or handle 10(represented by dotted lines on top of 2l) can be used and a pin in the slot instead of a lever, the pin ending at 38. The' lever 3 being in the position shown in Figs. l, 2, and S-that is, in the highest point in the vertical slot and held there by the compressed spring 6,

having its upward tendency-when it is desired to open the valve the lever is pressed downward and a little to one side or the other, depending on the way the horizont-al slots run, and then to the end 30 of the horizontal slot. In Fig. 5 the opening 25 in the case which admits the gas corresponds to the opening l5 and then to the hole l) to the burner. From this poi-nt the gas can be closed off from the burner as muchas desired-say three-fourths--that is, oneiiourth ofthe receivingehole left open. Thispeint depends on the point 31 in the slot, for as vsoon as the center of 4the lever 3 passes the point 3l the lever, iinpelled by'the spring through the slide, automatically raises the slide and lever to the position of 3, (shown in Fig. 5,) which eiectually closes the last onefourth of the opening. This prevents the turning of the gaslight so low that a draft of air can blow it out, or if another valve on the saine line of pipe were opened and the pressure removed from this jet by the ilow from the other it would go out, and when the other jet was turned ofi again the gas would escape from this and probably cause daniage. Then the valve is closed, it Cannot be opened by accident or a light touch. lt is necessary to intentionally Apress downward and to one side on the lever 3 to open it, thus securing against accidents.

The slide 23 is as tight a joint in the ease 24 as can be. To be consistent with its moving up and down, it also has the slope in the upper part of the case, which corresponds with the cone shape 22 of the piece This cone pressed in the slope by the spring 6 also makes a perfectly-tightjoint to prevent leaks,

and the slope also lirnits the distance which the slide can inove upward, and the slotlimits the distance downward. 1i. Vwhen closed `the spring G should break, the slide from gravity will drop and the lever 3 drop inthe small hollow 28 and the valve vstill remain closed, as the position occupied by the openings will be. as 15 and 17in Fig. S, and the spring can also be repaired and replaced by u'nscrewing the cap 35 and putting in another spring and replacing the cap without interfering with the valve, the same being closed the whole time.

This valve can be used wherever any ordinary gas-cock is used and in as many forms. The openings in the slide bearing the saine relation to the openings in the case, the only change necessary is 'in some instances to deliverthe gas from the top through the hole 19 and in others to deliver the gas from the other end of the same hole, as the inlet, as shown in Fig. 3. The case has a pipe connection on opposite sides, and the delivery and receiving holes in the ease are directly opposite each other, and the hole 20 in the valveslide passes through the center of said slide. The lever serves the double purpose of a controlled or directed pin i-n the slot `in 5, and for turning the valve-slide-any wheel or piece can be put on the top, as shown by the dotted lines 40, to turn the val ve in place'o-f usingthe lever.

This valve -enlargedfcan be 'used for steam er liquids, for in 'steam and Water valves-and cocks there is :a constant wearing on the seat of the valve, which renders lit useless unless repaired; but with our improvement the-action on the seat is removed andthe only wear from lise would be on'thesid-es of the openings without van y material damage Ato the Valve-joint.

' Having thus describedour invention, what we claim, and vdesire to secure by Letters Patent, is-

l. Ina gas, water, or steam valve the coinbination with t-helease, the slide,`the lever or pin 3, the slot or opening, the different features designated by the numbers 28, 29, 30, and v3l, for the purpose of limiting the-moveni'ent of ythe lever 3,and'the iinpe'lling-spring for `the purpose of closing vthe ports in the case when the lever is `moved Vfrom 30 tojust past-3l, as set forth and-described in the foregoing drawings and specification.

2. In a gas, water or steam valve the coinbination ot' lthe ease having one or more ports, the slide the horizontal open-ing 20, yi-n 'connection with the upright opening 19, vthe grou nd-joint 22 to prevent leaking, thespri'n g, the springeguide 33, and the cap, and the spring-'guide inthe eap,.36 asset `for-th and described i n the foregoing drawings 'and'speciiication.
